HOUSEHOLD OZONIZER `Application led October 26,l 1927. vSerial No. 228,797.

This invention relates to f household ozonizers.

An object of the invention is to provide in a single unitary structure and within the compact compass of the ordinary household refrigerator cabinet, a combined mechanical vrefrigerator and ozone generator so constructed and arranged that the ozone may be optionally distributed within the refrigerator cabinet or to the exterior thereof.

A further object of the invention is to provide means whereby the mechanical features of the refrigeratin-g unit are utilized for the' operation of an'ozonizer incorporated into the refrigerating installation.

Other objects of this invention will in part be obvious and in part hereinafter pointed out. The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the followin claims. 1

In the accompanying drawings, in `which is shown one of the various possible illustrative embodiments of this-invention, v Fig. 1 is a'front elevational view of a refrigerator cabinet, with the ozone generator incorporated therein in accordance with the invention, the doors of the cabinet being shownopen to illustrate the interior construction thereof.

Fig. 2 is a horizontal sectional view on the line 2 2 of Fig. 1, illustrating the machinery la out in the llower compartment of said ca inet. v .l

Fig. 3 is a sectional view on line 3-3 of Fig. 1, in which the disposition of the ozone apparatus and its associated chambers is shown, the door of the ozone compartment being shown in section toshow a feature of the inventlon.

5 type ordinarily found. in lthe household manner.

lOn the drawings, a cabinet 10 is shown comprising three levels, viz.; machinery mechanical refrigerator, while the ozone level 16 is an element which' may be made integral with, or as a separate member detachable from, the cabinet 10.

In the' machinery compartment 12 is 5:! housed the customary electric motor 18, driv lng the refrigerator compressor 20 by means of the belt 22 carried on pulleys 24, 26. In the present construction, the shaft 28 ofthe compressor 20 is extendedA to have mounted 60 thereon one element 30 of clutch 32, the other element 34 thereof bein adapted tol be fastened to the shaft 36 o an air pump 38.

Element 34 of' chtch 32 is formed W1th a collar 40 having a annular groove 42, in 65 which are received the prongs 44 of the arm 46, pivoted at 48 to a bracket 50 secured to the body of compressor 38 in any suitable Linked to an end of arm 46 is the y, actuating bar 52, slida'bly received in guide 70 54 and having a handle 56 formed at an end thereof. By means 'of handle 56 and bar 52,'

elements 30 and 34 of clutch 32 may be movede in and outvof engagementito control the operation of air pump 38. 4 75| The discharge outlet 58 of the' air pump 38 Ihas communicationrwith the pipe 60, here shown to extend upthrough the storage chamjber 14 of the cabinet 10, and then into the ozone level 16. f

Within the storage'chamber'14 is mounted the refrigerant tank 62, having the usual drawers 64 forv receiving materials to be subvjected to intense refrigeration. Due yto the refrierant contained in tanks 62, the surroun 'ng air in chamber 14 will be cooled and an induced circulation of air around such chamber will be caused, some of the chilled air passing pipe 60, and cooling the compressed air in said. pipe as it passes from pump 38. The usual shelvin 6'6 may lbe provided within storage cham r 14. The motor-918, the compressor 20, and the usual condenser and evaporator constitute the refrigerating uni't for the refrigerator.

The ozone level 116 of said cabinet is here shown as divided into three sections, namely, .the storagev compartment 68, a Water purifying compartment 70, and the ozonizer chamberl 72. These several sections may be insu- IiJU lated from each other by walls 74, 76, and from the storage chamber 14`by the floor 78, in which, if desired, suitable openings 79 may be provided for conducting heat from said lsections into the storage chamber' 111 for cooling purposes.

The ozonizer 73 housed in chamber 72 may be of any standard construction, and is here shown to comprise a sealed container 80, in which the ozone making apparatus is housed, and with which the end of pipe 60 has open communication. An outlet 82 from said container is connected by the pipe 84 with the storage and water purifiyng compartments G8, 70, by means of which ozone produced by said ozonizer 73 is conducted to said compartments, the flow of ozone to the respective compartments being controlled by means of the cocks, 86, 88. A cock 90 is connected to the bottom of container 80 and opens into storage chamber 14, so that a controlled flow of ozone to said chamber may be had.

By means of a pet cock 92, ozone produced by said ozonizer may be led into the compartment 72, in which said ozonizer is housed. Compartment 72 is provided with ay door 96 hinged to swing outwardly and secured normally by the lock device 98. S'aid door may be provided with a number of openings 100, with which is associated the louvre device 102 for controlling the effective size of said openings. With this assembly, it is possible to have a flow of ozonized air from the refrigerator into the roonrin which it may be installed, while, at supplied to compartments 68, 70, and chamber 14. 4

By shutting cocks 86, 88, and 90, and opening cock 92, ozone may be supplied only to the space in which cabinet 10 `is housed.

f Likewise, by reversing the valves, ozone is fed to the several chambers, while cut off The proportion of air mixing with ozone fed to the room and the rate of diffusion into the room may be controlled by the louvre device 102.

The water purifier compartment 70 may be of any desired construction, but is here shown as comprising a chamber defined by the walls 74, 76, and housing therein the assemblcd water tank 104: having 'a discharge outlet 106, of any well nection from the pipe 84 to said tank for purification purposes is here shown as made by the flexible tube. 108, which, if desired, may have suliicient length to be immersed to any desired level in the water contained in said tank. However, it is possible, by merely discharging ozone into compartment and securing surface contact between the water and the ozoneesaturated air of said compartment, that the water in tank 104 will absorb ozone sufficiently for purification purmyposes.

known type. Con- 68-is a chamber of any prethe same time, ozone is warf/.zee

ferred type in which may be stored perishable articles, or articles that may easily de teriorate and require the presence of a germ killing reagent, such as ozone to prevent de cay. The compartments, 68 and 70, may be provided with separate doors, as has been shown for compartment 72, but preferably a single door 110, provided with the customary latch device, closes both compartments G8 and 70 at once.

1n providing power for the operation of the electric motor 18, and for the ozonizer 73, any suitable conduit means 112 may be built into the cabinet 10, a switch 1111 being mounted on the front Wall 116 for controlling the czonizer 73.

1n operation, after power has been applied to ozonizer 73 by actuation of switch 1111, clutch 32 is actuated to place pump 38 into operation. However, if a concentrated ozone is desired, said pump may be left inactive.

1t will thus be seen that there is provided a device in which the several. objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, l
